The program enters an infinite loop at the function buf_prealloc

[Jim]

      I used nrf52832 sdk14.2 development, modified on the basis of the ble_app_template project, and ported some of the user code previously in sdk12.3 to sdk14.2.
     After I open the log function, I will enter an infinite loop at the function buf_prealloc(). As shown in the attached picture, sdk_config.h is shown in the attached file. What could be the cause? How can I fix this?err picture.zipsdk_config.h

It is difficult to say why this happens without being able to debug. If you upload your code I might be able to figure out why this happens.

Best regards,
